\subsection{Conceptual model}
\begin{center}
	\emph{This applies to section 9 and 19.}
\end{center}
Our conceptual model is simplified as much as possible. The model now consists of two entities with one attribute each and a relation between those two entities with three attribute.

The first thing we did after reading the initial assignment description was making various models. These were extensive, informal models which included all factors we thought were important for the process. \\
\\
From there we started to strip these models until we eventually got what we thought was a potential conceptual model. We discussed this model with our supervisor, but he informed us that the conceptual model was supposed to be much more simple and less detailed.	\\
\\
We removed various entities from the model like Floral Direct which just published the orders received from the clients onto their website, a database with lock system as described in the assignment (receiving and sending data from the Floral Direct website) and a lowest bidder who receives an email if he wins the bidding. These were removed because they only had something to do with the total picture of the model, but not with the specific part of the model we were investigating. \\
\\
We ended up with a conceptual model consisting of a \texttt{Client} which places an order to an \texttt{Order Handling System}, a \texttt{Local Company} which bids on these orders, a big 'black box' called \texttt{Order Handling System} which organizes everything and an \texttt{Order Contract} which is determined by the \texttt{Order Handling System}. \\
\\
In a final review, we decided together with our supervisor to change the conceptual model into an Entity-Relationship model. We created entities \texttt{Company} and \texttt{Order}, each with their own unique \texttt{ID} attributes with a \texttt{Bid} relation between them. This bid relation also has \texttt{Timestamp} and \texttt{Price} attributes.
